Allow recurring completion tasks to have day selection option (ie. Biweekly after completion on Fri)
For tasks that recur upon completion, allow the option to select which day the user wants the task to recur (ie. biweekly after completion on a Friday). Right now the recur upon completion tasks only allows selection for number of days past completion (ie. 2 or 3 days after completion).
Sometimes tasks get completed off schedule, and would be nice to not have an off-schedule chain to follow that one-off occurrence, and allowing the recur task to reset on its original schedule.
